In this lesson students are introduced to the concept of specific heat. This is done through notes, demonstrations, and practice questions.
For this lesson various resources are needed for the demonstrations including:
To engage students in this lesson I have them perform two different review activities.
To begin the new material for the lesson I have students begin to explore what they already know about specific heat.
I do this by showing students the first slide of the PowerPoint which has a picture of a playground and the question, "It is a warm day and you go to the park. Is everything going to feel the same? Why/Why not?"
I tell students to take about 3 minutes to try to answer the question on their own by jotting down a few ideas at the top of their notes organizer.
As they are getting done with this I tell them to turn to one of the partners at their table and discuss the question. I tell them that if there partner has some insight that they can feel free to change their answers that they wrote down.
After giving student a few minutes to talk with their partners I call on a few groups to share out their ideas.
Some of the examples of what students say include, "the metal parts feel hotter", and "the slide is really hot".
This is an example of one student's responses on the top of their Graphic Organizer.
For this section of the lesson I introduce the concept of specific heat and the idea that it plays are role in how quickly substance "heat up".
In this section of the lesson I elaborate on the idea of heat capacity through performing a demonstration for students. The demonstration is on the 5th slide of the PowerPoint and at the bottom of the first page of their graphic notes organizer.
To help students better understand how to use the specific heat equation and its purpose I do another demonstration of how to figure out the amount of Calories in a burning hot Cheeto.
I first have 3 students perform the lab for the entire class.
I then lead the students through the analysis questions.
This is an example of one student's filled in graphic organizer with answers to the Cheeto Lab demonstration.
To evaluate student learning I have them perform homework related to heat capacity.
